Nilfisk Solution Valve Not Closing

Solution continues to flow or drip from jets even when trigger is released

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Stuck or worn solenoid valve, Debris in valve seat, Damaged trigger valve in hand tool, Excessive pump pressure

Safety first: Disconnect power and relieve pressure by triggering the wand with the machine off.

Clean jets and valve: Remove spray jets and clean them. If dripping persists, inspect the solenoid valve or mechanical valve for debris and clean the seat.
Inspect hand tool trigger: If the issue is only with the hand tool, replace the trigger valve assembly.
Replace solenoid valve: If the valve coil energizes and de‑energizes correctly but water still passes, replace the Nilfisk solution solenoid valve.
